A request from IMA Financial Group:
They regularly need to engage in project opportunities that are more sensitive in nature in which they need to more significantly limit view/engagement of the project even among admins.
The enhancement request would be an extension of the 'Mark Private' function at the section level, where an admin/super admin would be able to mark an entire project as private and prevent other admins from being able to view/interact with the project in any way. Ideally only the initiating-admin (or super admin) and anyone they specifically invite would be granted view/access to the project.
The section level piece isn't enough for this use case as admins can still view project documents, about page, etc.
Please let me know if there are further questions.
